    ELISA using diluent A recommended for serum:

    Recombinant full length Osteomodulin (R&D systems, 2884-AD-050, lot NFV031506A) at the same concentration as the standard curve

    Two human serum samples in duplicate, diluted 1:2, 1:4, 1:8, and 1:16 (suggested 1:2)

    ELISA using diluent C recommended for culture supernatant:

    Four supernatants of osteoblasts culture, in duplicate, diluted 1:1, 1:3, and 1:9

    Negative Control

    Sample diluent

    one guinea pig serum sample in duplicate, diluted 1:2, 1:4, 1:8, and 1:16 (cross-reactivity unknown)

    Notes

    ABIN4884045 recognizes human osteomodulin in culture supernatant and recombinant human osteomodulin but not in human serum.

    Full Protocol
    • Reagent preparation and the assay are carried out according to the manufacturer’s instructions.
    • For the spike control prepare a 40ng/ml solution of standard protein using diluent A. Dilute standard twofold in undiluted, 1:2, 1:4 and 1:8 diluted serum to achieve a final serum dilution 1:2, 1:4, 1:8, and 1:16 in 100µl total volume using diluent A.
    • Add 100μl of the standard or the sample to each well.
    • Incubate for 2.5h at RT shaking at 500rpm.
    • Aspirate the solution in the wells and wash wells 4x with 350µl wash buffer.
    • Add 100μl of the biotinylated detection antibody to each well and incubate for 1h at RT shaking at 500rpm.
    • Aspirate the solution in the wells and wash wells 4x with 350µl wash buffer.
    • Add 100μl of the HRP conjugate to each well and incubate for 45min at RT shaking at 500rpm.
    • Aspirate the solution in the wells and wash wells 4x with 350µl wash buffer.
    • Add 100µl of the substrate reagent in dim light and incubate plate for 30min at RT protected from light.
    • Add 50µl of the stop solution to each well in the same order the substrate reagent was added.
    • Read OD450 immediately using a Multiskan GO (Thermofisher Scientific).
    Experimental Notes
    • The standard curves in the different diluents don’t look like the figure in the kit insert: OD450 were lower, but are good, with good duplicate reproducibility (A).

    • The curve with recombinant full length Osteomodulin from R&D Systems gives higher ODs than the standard protein from the kit.

    • ABIN4884045 allows detection of Osteomodulin in culture supernatants, in undiluted wells with values around 3-12ng/ml. This concentration appears very low but possible.

    • Serum values remain below the blank values and are not detected by the detecting antibody as confirmed with western blot, contrarily to standard protein, recombinant protein and culture supernatant (C).

    • The ABIN4884045 detection antibody recognizes osteomodulin from the kit standard and human recombinant osteomodulin which in a western blot. It also detects osteomodulin from human osteoblast culture supernatant but the signal is weak. However, in serum there is no signal after immunodetection although we can see that there is the correct transfer of total protein on the blot. The same western blot procedure with a different commercial antibody (R&D systems, BAF2884) gives good results in these human serum samples (Sanchez C (2018)).

    • Furthermore, a substantial matrix effect of serum makes the spiking of 20ng/ml recombinant Osteomodulin undetectable, even in 1:16 serum dilution with diluent A before adding the Osteomodulin. Recovery of Osteomodulin in serum samples is 0% even at a 1:16 dilution.
